江苏省吕四港渔民艾滋病/性病高危行为流行病学研究

摘要

Objective To investigate the high-risk behaviors related to acquared immune deficiency syndrome/sexually transmitted disease (AIDS/STDs) infection among fishermen in Lv-si harbor,Jiangsu province.Methods A cross-sectional study was designed to investigate the research participants' demographic characteristics,high-risk behaviors that related to AIDS/STDs.Logistic regression was performed to measure the associations between potential risk factors and reported potential high-risk sexual behavior.Results 817 fishermen participated in the study and casual or commercial sex activities appeared to be the main high-risk behavior for AIDS/STDs infection in the target population.The rates of casual and commercial sex reported were 18.1％ and 28.9％ among fishermen.Risk factors associated with AIDS/STDs related high-risk behaviors among fishermen were high mobility (OR=1.516,P=0.038),higher lifetime sex frequency (OR=1.422,P=0.002)and unmarried status ( OR =7.527,P=0.014).Protective factors against high-risk behaviors were low intake of alcohol (OR=0.803,P=0.053),negative STD history (OR=0.268,P=0.001 ),age of initial sexual intercourse at or older than 22 years (OR =0.440,P=0.000) of age,as well as negative attitude toward multiple sexual parmers (OR=0.662,P=0.023 ) and legitimation for commercial sex (OR=0.612,P=0.007).Conclusion There were risk behaviors of AIDS/STDs in those infected fishmen.Casual and commercial sex were common high-risk behaviors.%目的 了解江苏省吕四港地区渔民艾滋病/性病相关高危行为,分析其影响因素.方法 以横断面调查方法收集目标人群的人口学信息、艾滋病/性病高危行为及潜在影响因素等信息,采用非条件logistic回归分析高危行为的影响因素.结果 共有817名渔民参与调查.临时性行为和商业性行为是渔民感染艾滋病/性病的主要高危行为,报告率分别为18.1％和28.9％.渔民高危性行为的危险因素:流动性(OR=1.516,P=0.038)、平时性生活频次高(OR=1.422,P=0.002)、离异或丧偶婚姻状态等(OR=7.527,P=0.014);保护因素有饮酒少(OR=0.803,P=0.053)、无性病史(OR=0.268,P=0.001)、初次性行为≥22岁(OR=0.440,P=0.000)、不接受多性伴(OR=0.662,P=0.023)和商业性行为合法化的态度(OR=0.612,P=0.007).结论 渔民中存在着感染艾滋病/性病的风险;临时性行为与商业性行为是常见的高危行为.
